We report optical spectroscopy of 10 supernova discovered by the Dark Energy Survey (ATel #4668). The spectra (425-1050) were obtained using the LDSS3 on the 6.5m Clay telescope at the Las Campinas Observatory. Object classification was performed using SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) and superfit (Howell et al, 2005, ApJ, 634, 119), the details of which are reported in the table below.
